Abstract: This disclosure relates to fractional-N phase-locked loops. A digital filter can filter out quantization noise from a modulator. Separate paths can process an integer part associated with an output signal of the digital filter and a fractional part associated with the output signal of the digital filter. The separate paths can be combined in the fractional-N phase-locked loop, for example, as a weighted sum.

Abstract: A power conversion apparatus or system can be configured to receive a high voltage alternating current (AC) signal at an input and to provide in dependence thereon a low voltage direct current (DC) signal from an output stage. The power conversion apparatus can include a main path comprising a high voltage capacitor in series with the input. In an example, the capacitor comprises a portion of an electric field energy harvesting system.

Abstract: A cap for use with devices, such as sensors. The cap includes protrusions on its underside, to restrict the movement of a liquid or a gel placed under cap. The protrusions may take the form of walls or pillars, depending on the application. As such, the cap retains the liquid or gel in a specified position on the device. For example, an electrochemical sensor may require a liquid electrolyte to remain in place over one or more electrodes. The protrusions may not extend far enough to touch the device, but rather leave a small gap. However, because of the surface tension of the liquid, the liquid generally stays within the protrusions.

Abstract: Aspects of this disclosure relate to controlling one or more vehicle systems based on a determined weather condition. In some embodiments, a radar system can be mounted on a vehicle and can collect weather data by receiving electromagnetic signals. A weather condition can be determined based on the collected weather data, and a vehicle system can be controlled based on the determined weather condition, such as vehicle lighting, windscreen wipers, or cruise control. In some embodiments, weather conditions can include fog, sleet, or smog. The weather condition can be determined by analyzing scattered reflections from incident microwaves and/or radio waves to determine a level of attenuation of the scattered electromagnetic energy indicative of a presence or absence of particles. A map can be displayed displaying the weather condition and controlling vehicle navigation systems. The collected weather data can be compared with data from a LiDAR or camera system for reliability.

Abstract: Techniques to use reservoir capacitors in ADC to supply most of the charge to bit-trial capacitors as bit-trials are performed. An accurate reference voltage source, e.g., a reference buffer circuit, only needs to supply the difference, e.g., an inaccuracy, in the charge supplied by the reservoir capacitors. Instead of having to resettle for each bit-trial, the accurate reference voltage source has only to deliver the initial charge to the reservoir capacitors during acquisition and once more when the ADC is ready to sample onto the residue amplifier. These techniques can ease the demands on the reference buffer circuit and requirement of external decoupling capacitors, for example.

Abstract: A system and method for operating a high dynamic range analog front-end receiver for long range LIDAR with a transimpedance amplifier (TIA) include a clipping circuit to prevent saturation of the TIA. The output of the clipping circuit is connected via a diode or transistor to the input of the TIA and regulated such that the input voltage of the TIA remains close to or is only slightly above the saturation threshold voltage of the TIA. The regulation of the input voltage of the TIA can be improved by connecting a limiting resistor in series with the diode or transistor. A second clipping circuit capable of dissipating higher input currents and thus higher voltages may be connected in parallel with the first clipping circuit. A resistive element may be placed between the first and second clipping circuits to further limit the input current to the TIA.

Abstract: Various examples are directed to a digital predistortion (DPD) circuit comprising a DPD actuator circuit, a DPD feedback frequency-shaping filter, a basis matrix generator circuit, a basis matrix frequency-shaping filter, and a DPD adaption circuit. The DPD actuator circuit may generate a predistorted signal based at least in part on an input signal and a set of frequency-shaped DPD parameters. The DPD feedback frequency-shaping filter may filter a DPD feedback signal to generate a frequency-shaped DPD feedback signal. A passband of the DPD feedback frequency-shaping filter may include substantially all of a bandwidth of the input signal and exclude a distortion term outside the bandwidth of the input signal. The basis matrix generator may generate a basis matrix based at least in part on a power amplifier feedback signal The basis matrix frequency-shaping filter may generate a frequency-shaped basis matrix based at least in part on the basis matrix. The DPD adaption circuit may be configured to generate the set of frequency-shaped DPD parameters based at least in part on the frequency-shaped basis matrix and the frequency-shaped DPD feedback signal.

Abstract: Techniques are provided for compensating gain of a combined amplifier and analog-to-digital converter (ADC) circuit, for example, due to additional filtering added to an input of the circuit. In an example, an integrated circuit including an amplifier and ADC can include an amplifier circuit configured to receive an input signal and to amplify the input signal based on an input resistance and a feedback resistance, and to provide an amplified representation of the input signal, and an ADC circuit configured to receive an output of the amplifier, to determine a digital coefficient associated with an additional input resistance coupled to the amplifier, and to provide a compensated digital representation of the amplified representation of the input signal using the digital compensation coefficient.

Abstract: Shortening any of the operational phases of a noise-shaping successive approximation register (SAR) analog-to-digital converter (ADC), including the acquisition phase, the bit trial phase, and the residue charge transfer phase, can result in higher power, and it can be difficult to achieve high speed at low power. Using various techniques described, the acquisition, bit-trial, and residue charge transfer phases of two or more digital-to-analog converter (DAC) circuits of an ADC circuit can be time-interleaved. The use of two or more DAC circuits can increase or maximize the time available for the acquisition, bit-trial, and residue charge transfer phases.
